You are the architect of the Contoso airline group. You are responsible for designing a big data solution. This design needs to focus on the ingestion portion. You expect millions of events per second to be ingested and processed. You need to decide which technology will be able to ingest these large amounts of data and temporary store and process them. Which of the following technologies would be the best for the design?
Event Hub is correct, as this allows large quantities of events to be ingested, processed and temporarily stored. Event Grid would not suffice as this is used to provide developers access to the events generated by cloud infrastructure. Notification Hub will not suffice as this is used to send PUSH notifications on a large scale. Service bus will not suffice, as this is a messaging service and not an ingestion and processing service.
